where can i get more information on internet about asian beetles?
The multicolored Asian lady beetle (Harmonia axyridis) is native to Asia but occurs in many areas of the United States. This beneficial insect was imported and released as early as 1916 in attempts to naturally control certain insect pests. But the first populations were not found in this country until 1988 in Louisiana near the busy port of New Orleans. Over the years, federal, state and private entomologists released the insect at a number of locations. But it was not detected in these places until some years after it had became established in Louisiana. In addition, accidental entries have occurred via imported nursery items at ports in Delaware and South Carolina. Thus, it is uncertain whether the beetle’s establishment resulted from planned releases, accidental entries or both. For more information, visit: http://www.ars.usda.gov/is/br/lbeetle/ Sources:
Asian long-horned beetle: The Asian longhorned beetle (Anoplophora glabripennis) (ALB) is native to China and other areas of the Far East, where it causes widespread mortality of poplar, willow, elm and maple trees. The beetle, known as the Starry Sky or Sky Oxen beetle in China, is a large black insect, with white spots dashed irregularly on its elytra (wing covers). Adults are typically 1–1.5 inches (2.5–3.8 cm) long. The distinctive long antennae that give the beetle its common name are as long as the body in females and almost twice the body length in males. The ALB is considered an invasive species in North America, where it is a serious threat to many species of deciduous hardwood trees. During the larval stage, the ALB bores deep into a tree’s heartwood, where it feeds on the tree’s nutrients. The tunneling damages and eventually kills the tree. Infestations in the United States: Adult ALBs can be seen from late spring to fall, depending on the climate. The ALB was first discove
